Was working fine and then not able to sync at all.  Only changes were adding a couple of play lists (which would take approximately 5 seconds to select in the sync settings, locking up).  Now my cheapo mp3 player is also having the same issues.

Solved it deleting all contents on my device under the synced folders.
